To solve this problem, we need to subtract the given quantities just like how we do normally with numbers. However, in this case, we need to carry over when the fluid ounces reach 8 to complete a cup.
7 c 3 fl oz – 3 c 4 fl oz
= 6 c 16 fl oz + 1 c 3 fl oz – 3 c 4 fl oz (converting cups to fluid ounces)
= 6 c 15 fl oz + 11 fl oz – 3 fl oz (grouping fluid ounces separately)
= 6 c 13 fl oz (subtracting the fluid ounces)
Therefore, the answer is C. 3 c 1 fl oz.
7 c 3 fl oz – 3 c 4 fl oz
A. 4 c 1 fl oz
B. 3 c 7 fl oz
C. 3 c 1 fl oz

3 + 8 is not 16
6 c 11 oz - 3 c 4 oz = 3 c 7 oz
6 c 11 oz - 3 c 4 oz = 3 c 7 oz
